It's not our dogs, it's the poor dogs next door who are in a kennel all day and let out at night as 'guard' dogs. Ours are also outdoor dogs and don't bark at all, but the neighbour's dogs are driving me crazy with their barking through our mutual fence.
We have a night guard and I was thinking of asking him to use a small hand held garden water spray to spray them when they are barking near the fence.
Would that work? Any other suggestions?
